Adding fuel-injection to your classic car just got easier with the Atomic EFI from MSD. The Atomic EFI is the fastest way to quicker starts, smoother idle and immediate throttle response. Available in several configurations as complete kits, each throttle body injection unit is packed with features designed to enhance performance and reliability.
An internal fuel rail reduces leaks and provides a sleek appearance. Annular rings improve fuel atomization and ensure the best air/fuel mixture is delivered to each cylinder. The square-bore design features large 1.75" diameter throttle blades that are riding on precision roller bearings for a smooth pedal transition. The self-calibrating throttle position sensor and four 80-lb injectors ensure that fuel is delivered at the correct rate. Wiring is reduced by integrating the ECU and most sensors into the throttle body. The only sensors you’ll need to connect are the O2 and coolant temperature. The compact power module is a simple plug-in device that can control the electric fuel pump and two electric fans. A hand-held programmer provides a hassle-free way to custom-tailor the EFI to your engine and monitors all of the vitals during operation.
